The medical application connector (10), the connector itself (12) with, the connector itself (12) from the branching section branching (16) with it has. The connector itself (12), the connector itself (12) the communication path which communicates the inside and outside (21) is formed in the fuselage section. The branching section (16), the rotary tubular section which revolution possibly is jointed to the fluid-tight (62) with, the rotary tubular section (62) the side port (80) it forms the channel which reaches from the inner skin the communication path (21) the connector itself (12) vis-a-vis at the position where it covers and at the same time the connector itself (12) the lumen (24) with the branching lumen which is communicated (68) with it possesses.医療用コネクタ(10)は、コネクタ本体(12)と、コネクタ本体(12)から分岐した分岐部(16)とを備える。コネクタ本体(12)の胴体部には、コネクタ本体(12)の内外を連通する連通路(21)が形成されている。分岐部(16)は、連通路(21)を覆う位置でコネクタ本体(12)に対して回転可能に液密に接続した回転管状部(62)と、回転管状部(62)の内周面からサイドポート(80)に至る流路を形成し且つコネクタ本体(12)のルーメン(24)と連通する分岐ルーメン(68)とを有する。
